BACKGROUND OF THE INVENTION

The invention relates to heat transfer compositions, and in particularto heat transfer compositions which may be suitable as replacements forexisting refrigerants such as R-134a, R-152a, R-1234yf, R-22, R-410A,R-407A, R-407B, R-407C, R507 and R-404a.

The listing or discussion of a prior-published document or anybackground in the specification should not necessarily be taken as anacknowledgement that a document or background is part of the state ofthe art or is common general knowledge. Mechanical refrigeration systemsand related heat transfer devices such as heat pumps andair-conditioning systems are well known. In such systems, a refrigerantliquid evaporates at low pressure taking heat from the surrounding zone.The resulting vapour is then compressed and passed to a condenser whereit condenses and gives off heat to a second zone, the condensate beingreturned through an expansion valve to the evaporator, so completing thecycle. Mechanical energy required for compressing the vapour and pumpingthe liquid is provided by, for example, an electric motor or an internalcombustion engine.

In addition to having a suitable boiling point and a high latent heat ofvaporisation, the properties preferred in a refrigerant include lowtoxicity, non-flammability, non-corrosivity, high stability and freedomfrom objectionable odour. Other desirable properties are readycompressibility at pressures below 25 bars, low discharge temperature oncompression, high refrigeration capacity, high efficiency (highcoefficient of performance) and an evaporator pressure in excess of 1bar at the desired evaporation temperature.

Dichlorodifluoromethane (refrigerant R-12) possesses a suitablecombination of properties and was for many years the most widely usedrefrigerant. Due to international concern that fully and partiallyhalogenated chlorofluorocarbons were damaging the earth's protectiveozone layer, there was general agreement that their manufacture and useshould be severely restricted and eventually phased out completely. Theuse of dichlorodifluoromethane was phased out in the 1990's.

Chlorodifluoromethane (R-22) was introduced as a replacement for R-12because of its lower ozone depletion potential. Following concerns thatR-22 is a potent greenhouse gas, its use is also being phased out.

Whilst heat transfer devices of the type to which the present inventionrelates are essentially closed systems, loss of refrigerant to theatmosphere can occur due to leakage during operation of the equipment orduring maintenance procedures. It is important, therefore, to replacefully and partially halogenated chlorofluorocarbon refrigerants bymaterials having zero ozone depletion potentials.

In addition to the possibility of ozone depletion, it has been suggestedthat significant concentrations of halocarbon refrigerants in theatmosphere might contribute to global warming (the so-called greenhouseeffect). It is desirable, therefore, to use refrigerants which haverelatively short atmospheric lifetimes as a result of their ability toreact with other atmospheric constituents such as hydroxyl radicals oras a result of ready degradation through photolytic processes.

R-410A and R-407 refrigerants (including R-407A, R-407B and R-407C) havebeen introduced as a replacement refrigerant for R-22. However, R-22,R-410A and the R-407 refrigerants all have a high global warmingpotential (GWP, also known as greenhouse warming potential).

1,1,1,2-tetrafluoroethane (refrigerant R-134a) was introduced as areplacement refrigerant for R-12. However, despite having no significantozone depletion potential, R-134a has a GWP of 1300. It would bedesirable to find replacements for R-134a that have a lower GWP.

R-152a (1,1-difluoroethane) has been identified as an alternative toR-134a. It is somewhat more efficient than R-134a and has a greenhousewarming potential of 120. However the flammability of R-152a is judgedtoo high, for example to permit its safe use in mobile air conditioningsystems. In particular it is believed that its lower flammable limit inair is too low, its flame speeds are too high, and its ignition energyis too low.

Thus there is a need to provide alternative refrigerants having improvedproperties such as low flammability. Fluorocarbon combustion chemistryis complex and unpredictable. It is not always the case that mixing anon-flammable fluorocarbon with a flammable fluorocarbon reduces theflammability of the fluid or reduces the range of flammable compositionsin air. For example, the inventors have found that if non-flammableR-134a is mixed with flammable R-152a, the lower flammable limit of themixture alters in a manner which is not predictable. The situation isrendered even more complex and less predictable if ternary or quaternarycompositions are considered.

There is also a need to provide alternative refrigerants that may beused in existing devices such as refrigeration devices with little or nomodification.

R-1234yf (2,3,3,3-tetrafluoropropene) has been identified as a candidatealternative refrigerant to replace R-134a in certain applications,notably the mobile air conditioning or heat pumping applications. ItsGWP is about 4. R-1234yf is flammable but its flammabilitycharacteristics are generally regarded as acceptable for someapplications including mobile air conditioning or heat pumping. Inparticular, when compared with R-152a, its lower flammable limit ishigher, its minimum ignition energy is higher and the flame speed in airis significantly lower than that of R-152a.

The environmental impact of operating an air conditioning orrefrigeration system, in terms of the emissions of greenhouse gases,should be considered with reference not only to the so-called “direct”GWP of the refrigerant, but also with reference to the so-called“indirect” emissions, meaning those emissions of carbon dioxideresulting from consumption of electricity or fuel to operate the system.Several metrics of this total GWP impact have been developed, includingthose known as Total Equivalent Warming Impact (TEWI) analysis, orLife-Cycle Carbon Production (LCCP) analysis. Both of these measuresinclude estimation of the effect of refrigerant GWP and energyefficiency on overall warming impact.

The energy efficiency and refrigeration capacity of R-1234yf have beenfound to be significantly lower than those of R-134a and in addition thefluid has been found to exhibit increased pressure drop in systempipework and heat exchangers. A consequence of this is that to useR-1234yf and achieve energy efficiency and cooling performanceequivalent to R-134a, increased complexity of equipment and increasedsize of pipework is required, leading to an increase in indirectemissions associated with equipment. Furthermore, the production ofR-1234yf is thought to be more complex and less efficient in its use ofraw materials (fluorinated and chlorinated) than R-134a. So the adoptionof R-1234yf to replace R-134a will consume more raw materials and resultin more indirect emissions of greenhouse gases than does R-134a.

Some existing technologies designed for R-134a may not be able to accepteven the reduced flammability of some heat transfer compositions (anycomposition having a GWP of less than 150 is believed to be flammable tosome extent).

A principal object of the present invention is therefore to provide aheat transfer composition which is usable in its own right or suitableas a replacement for existing refrigeration usages which should have areduced GWP, yet have a capacity and energy efficiency (which may beconveniently expressed as the “Coefficient of Performance”) ideallywithin 10% of the values, for example of those attained using existingrefrigerants (e.g. R-134a, R-152a, R-1234yf, R-22, R-410A, R-407A,R-407B, R-407C, R507 and R-404a), and preferably within less than 10%(e.g. about 5%) of these values. It is known in the art that differencesof this order between fluids are usually resolvable by redesign ofequipment and system operational features. The composition should alsoideally have reduced toxicity and acceptable flammability.

By “substantially no”, we include the meaning that the compositions ofthe invention contain 0.5% by weight or less of the stated component,preferably 0.1% or less, based on the total weight of the composition.

The compositions of the invention may contain substantially no:

(i) 2,3,3,3-tetrafluoropropene (R-1234yf),

(ii) cis-1,3,3,3-tetrafluoropropene (R-1234ze(Z)), and/or

The compositions of the invention have zero ozone depletion potential.

Surprisingly, it has been found that the compositions of the inventiondeliver acceptable properties for use in air conditioning, heat pump andlow and medium temperature refrigeration systems as alternatives toexisting refrigerants such as R-22, R-410A, R-407A, R-407B, R-407C, R507and R-404a, while reducing GWP and without resulting in highflammability hazard.

Unless otherwise stated, as used herein “low temperature refrigeration”means refrigeration having an evaporation temperature of from about −50to about −20° C. “Medium temperature refrigeration” means refrigerationhaving an evaporation temperature of from about −20 to about 0° C.

Unless otherwise stated, IPCC (Intergovernmental Panel on ClimateChange) TAR (Third Assessment Report) values of GWP have been usedherein. The GWP of selected existing refrigerant mixtures on this basisis as follows:

R-407A 1990 R-407B 2695 R-407C 1653 R-404A 3784 R507 3850

In an embodiment, the compositions of the invention have a GWP less thanR-22, R-410A, R-407A, R-407B, R-407C, R507 or R-404a. Conveniently, theGWP of the compositions of the invention is less than about 2800 Forinstance, the GWP may be less than 2800, 2500, 2300, 2100, 2000, 1900,1800, 1700, 1500 or 1400.

Preferably, the compositions of the invention have a GWP that is lessthan 1500, preferably less than 1400, more preferably less than 1300,1000, 900 or 700 or 500.

Advantageously, the compositions are of reduced flammability hazard whencompared to the individual flammable components of the compositions,e.g. R-32, propene or propane.

In one aspect, the compositions have one or more of (a) a higher lowerflammable limit; (b) a higher ignition energy; or (c) a lower flamevelocity compared to R-32, propene, propane or R-1234yf. In a preferredembodiment, the compositions of the invention are non-flammable (orinflammable).

Flammability may be determined in accordance with ASHRAE Standard 34incorporating the ASTM Standard E-681 with test methodology as perAddendum 34p dated 2004, the entire content of which is incorporatedherein by reference.

In some applications it may not be necessary for the formulation to beclassed as non-flammable by the ASERAE 34 methodology; it is possible todevelop fluids whose flammability limits will be sufficiently reduced inair to render them safe for use in the application, for example if it isphysically not possible to make a flammable mixture by leaking therefrigeration equipment charge into the surrounds. We have found thatthe effect of adding R-1234ze and R-134a/R-125 to flammable refrigerantsR-32, propene and/or propane is to modify the flammability in mixtureswith air in this manner.

Temperature glide, which can be thought of as the difference betweenbubble point and dew point temperatures of a zeotropic (non-azeotropic)mixture at constant pressure, is a characteristic of a refrigerant; ifit is desired to replace a fluid with a mixture then it is oftenpreferable to have similar or reduced glide in the alternative fluid.

In accordance with the retrofitting method described above, an existingheat transfer fluid can be fully removed from the heat transfer devicebefore introducing a composition of the invention. An existing heattransfer fluid can also be partially removed from a heat transferdevice, followed by introducing a composition of the invention.

In another embodiment wherein the existing heat transfer fluid isR-134a, and the composition of the invention contains R134a,R-1234ze(E), the second component, optionally R-125, and optionally thefourth component (and optional components such as a lubricant, astabiliser or an additional flame retardant), R-1234ze(E), the secondcomponent, any R-125 and/or the fourth component can be added to theR-134a in the heat transfer device, thereby forming the compositions ofthe invention, and the heat transfer device of the invention, in situ.Some of the existing R-134a may be removed from the heat transfer deviceprior to adding the R-1234ze(E), the second component, etc, tofacilitate providing the components of the compositions of the inventionin the desired proportions.

Preferably, this method comprises the stepof obtaining an allocation of greenhouse gas emission credit.

By environmental impact we include the generation and emission ofgreenhouse warming gases through operation of the product.

As mentioned above, this environmental impact can be considered asincluding not only those emissions of compounds or compositions having asignificant environmental impact from leakage or other losses, but alsoincluding the emission of carbon dioxide arising from the energyconsumed by the device over its working life. Such environmental impactmay be quantified by the measure known as Total Equivalent WarmingImpact (TEWI). This measure has been used in quantification of theenvironmental impact of certain stationary refrigeration and airconditioning equipment, including for example supermarket refrigerationsystems (see, for example,http://en.wikipedia.org/wiki/Total_equivalent_warming_impact).

The environmental impact may further be considered as including theemissions of greenhouse gases arising from the synthesis and manufactureof the compounds or compositions. In this case the manufacturingemissions are added to the energy consumption and direct loss effects toyield the measure known as Life-Cycle Carbon Production (LCCP, see forexample http://www.sae.org/events/aars/presentations/2007papasavva.pdf).The use of LCCP is common in assessing environmental impact ofautomotive air conditioning systems.

Emission credit(s) are awarded for reducing pollutant emissions thatcontribute to global warming and may, for example, be banked, traded orsold. They are conventionally expressed in the equivalent amount ofcarbon dioxide. Thus if the emission of 1 kg of R-134a is avoided thenan emission credit of 1×1300=1300 kg CO2 equivalent may be awarded.

In another embodiment of the invention, there is provided a method forgenerating greenhouse gas emission credit(s) comprising (i) replacing anexisting compound or composition with a composition of the invention,wherein the composition of the invention has a lower GWP than theexisting compound or composition; and (ii) obtaining greenhouse gasemission credit for said replacing step.

In a preferred embodiment, the use of the composition of the inventionresults in the equipment having a lower Total Equivalent Warming Impact,and/or a lower Life-Cycle Carbon Production than that which would beattained by use of the existing compound or composition.

These methods may be carried out on any suitable product, for example inthe fields of air-conditioning, refrigeration (e.g. low and mediumtemperature refrigeration), heat transfer, blowing agents, aerosols orsprayable propellants, gaseous dielectrics, cryosurgery, veterinaryprocedures, dental procedures, fire extinguishing, flame suppression,solvents (e.g. carriers for flavorings and fragrances), cleaners, airhorns, pellet guns, topical anesthetics, and expansion applications.Preferably, the field is air-conditioning or refrigeration.

Examples of suitable products include a heat transfer devices, blowingagents, foamable compositions, sprayable compositions, solvents andmechanical power generation devices. In a preferred embodiment, theproduct is a heat transfer device, such as a refrigeration device or anair-conditioning unit.

The existing compound or composition has an environmental impact asmeasured by GWP and/or TEWI and/or LCCP that is higher than thecomposition of the invention which replaces it.

This may depend on the environmentalimpact of the existing compound or composition being replaced and theenvironmental impact of the replacement composition of the invention.Preferably, the existing compound or composition in the product is fullyreplaced by the composition of the invention.

The invention is illustrated by the following non-limiting examples.

EXAMPLES Example 1

The performance of a composition comprising R-32 30%, R-125 25%, R-134a25% and R-1234ze(E) 20% (weight basis) was modelled for mediumtemperature and low temperature refrigeration applications (“Blend A”).The cycle conditions chosen were:

(a) Medium Temperature Application

Mean condensing temperature 40° C.Mean evaporating temperature −10° C.Suction line return temperature 15° C.

Subcooling 5K

Evaporator superheat 5KCompressor (isentropic) efficiency 65%Cooling duty 10 kWSuction line pipe diameter 22.7 mm

(b) Low Temperature Application

Mean condensing temperature 40CMean evaporating temperature −35° C.Suction line return temperature −10° C.

Subcooling 5K

Evaporator superheat 5KCompressor (isentropic) efficiency 65%Cooling duty 10 kWSuction line pipe diameter 22.7 mmTemperature for initiation of liquid injection to control compressortemperature: 130° C.

These conditions were chosen as representative of those found in asupermarket refrigeration system with air cooled condenser in Europeansummer conditions. The performance of Blend A is shown in Tables 1 and 2with the estimated performance of the commercially available andcommonly used refrigerants R-407C, R-407A and R-404A indicated forcomparison. The capacity, energy efficiency (as Coefficient ofPerformance) and suction line pressure drop are compared to a baselineof R-407C, as this refrigerant has the highest theoretical COP andlowest direct GWP of the established refrigerants.

It can be seen that this composition has comparable energy efficiencythan R-407C, better cooling capacity than R-407C, lower pressure dropand essentially comparable discharge temperature. Furthermore thecapacity and energy efficiency of the composition is superior to R-404A.The composition has lower GWP than R-407C and so the total environmentalwarming impact (TEWI) of a system using this fluid will be lower thanthat achievable using R-407C or R-404A.

The fluid further exhibits close match of performance parameters toR-407A, which is today finding increasing utility as a refrigerant toreplace R-404A. The operating pressures are very similar to those foundwith R-407A, so replacement of R-407A with this composition wouldrequire little or no change to a refrigeration system control scheme.

Furthermore the composition is believed to be essentially non-flammable.

Example 2

The performance was modelled for further compositions of the inventioncomprising: R-32 in range 20-35% w/w; R-125 in range 15-30% w/w; R-134ain range 15-50% w/w and R-1234ze being the balance, using the sameconditions as in Table 1 and with R-407C as the reference fluid forcomparison of capacity, energy efficiency and suction line pressuredrop. The compositions of the invention give acceptable or improvedperformance with lower GWP and lower overall TEWI than R-407A, R-407C orR-404A.

Example 3

The performance was modelled for further compositions of the inventionas explained in more detail below. The derivation of the model used isas follows.

The physical properties of R-1234ze(E) required to model refrigerationcycle performance, namely critical point, vapour pressure, liquid andvapour enthalpy, liquid and vapour density and heat capacities of vapourand liquid were accurately determined by experimental methods over thepressure range 0-200 bar and temperature range −40 to 200° C., and theresulting data used to generate Helmholtz free energy equation of statemodels of the Span-Wagner type for the fluid in the NIST REFPROP Version8.0 software, which is more fully described in the user guidewww.nist.gov/srd/PDFfiles/REFPROP8.PDF, and is incorporated herein byreference. The variation of ideal gas enthalpy of both fluids withtemperature was estimated using molecular modelling software Hyperchemv7.5 (which is incorporated herein by reference) and the resulting idealgas enthalpy function was used in the regression of the equation ofstate for these fluids. The predictions of this model R1234ze(E) werecompared to the predictions yielded by use of the standard files forR1234ze(E) included in REFPROP Version 9.0. It was found that closeagreement was obtained for each fluid's properties.

The vapour liquid equilibrium behaviour of R-1234ze(E) was studied in aseries of binary pairs with carbon dioxide, R-32, R-125, R-134a, R-152a,R-161, propane and propylene over the temperature range −40 to +60° C.,which encompasses the practical operating range of most refrigerationand air conditioning systems. The composition was varied over the fullcompositional space for each binary in the experimental programme,mixture parameters for each binary pair were regressed to theexperimentally obtained data and the parameters were also incorporatedinto the REFPROP software model. The academic literature was nextsearched for data on the vapour liquid equilibrium behaviour of carbondioxide with the hydrofluorocarbons R-32, R-125, R-152a, R-161 andR-152a. The VLE data obtained from sources (referenced in the articleApplications of the simple multi-fluid model to correlations of thevapour-liquid equilibrium of refrigerant mixtures containing carbondioxide, by R. Akasaka, Journal of Thermal Science and Technology,159-168, 4, 1, 2009) were then used to generate mixing parameters forthe relevant binary mixtures and these were then also incorporated intothe REFPROP model. The standard REFPROP mixing parameters for carbondioxide with propane and propylene were also incorporated to this model.

The resulting software model was used to compare the performance ofselected fluids of the invention with R-407A in a low temperaturesupermarket refrigeration cycle simulation. The use of liquid injectionto control compressor discharge temperature was included as a feature ofthis cycle. Liquid injection is recommended by compressor manufacturersand refrigerant suppliers if R-407A or R-22 is to be used in suchapplications.

The quantity of liquid required to maintain the compressor discharge gasat or below the desired maximum temperature was estimated by assumingthat the liquid to be injected to the compressor was at the samethermodynamic state as the liquid leaving the condenser and by thenperforming a heat balance on the machine. The total compression workrequired was then derived from knowledge of the total mass flow throughthe compressor and the specified outlet and inlet refrigerant states.

The comparison of fluids was carried out assuming equivalent meanevaporating and condensing temperatures for the refrigerants, and fixeddegrees of subcooling and evaporator superheat. Fixed pressure dropswere assumed for R-407A in the evaporator, condenser and compressorsuction gas line. The pressure drops for the fluids of the inventionwere then estimated for the same cycle by estimating the achievedcompressor throughput with the fluid, deriving the mass flowrate of therefrigerant in the line and then calculating the pressure drop bycomparison with the assumed pressure drop for the reference refrigerant.

To calculate the achieved compressor throughput for R-407A and thefluids of the invention, the compressor was assumed to be a piston typemachine running at fixed speed and known piston displacement with aneffective clearance volume ratio of 3% and an average adiabatic(isentropic) efficiency of 65%, operating at a constant compressorsuction gas temperature of 20° C. The volumetric efficiency of thecompressor was then estimated for each refrigerant from the pressureratio developed over the compressor and the thermodynamic properties ofthe gas using the standard relationship for estimation of volumetricefficiency in such a machine.

Using the model set out above, the performance of selected compositionsof the invention containing 16 to 40% by weight R-32, 10 to 24% byweight R-125, 16 to 28% by weight R-134a and 8 to 56% by weightR-1234ze(E) is shown in Tables 3 to 34 below.

Modelled performance of R-404A, R-407C, R-407D and R-407F is shown inComparative Table X immediately below.

It has been found unexpectedly that it is possible to achieve capacitiescomparable to those of R-404A or R-407F whilst operating at lowercondensing pressures than either R-404A or R-407F and at comparable orlower pressure ratios than those achieved with R-407A and R-407F. Infact some compositions of the invention offer pressure ratios comparableto R-404A.

The incorporation of R-1234ze(E) to the fluid further allows a reductionof GWP of the mixture compared to the GWP of any of the R-407 fluids andcompared to R-404A. R1234ze(E) is unsuitable in its own right for thisapplication given its (relatively) high boiling point of −19° C.Surprisingly, therefore, it has proved possible to use significantquantities of R-1234ze(E) in the compositions of the invention withoutdetrimental effect on the operating pressures of the fluids.

Therefore, the fluids of the invention offer highly unexpectedsignificant improved environmental performance when compared tocomparable known EFC refrigerants (e.g. R-407A, R407F and R-404a) on thegrounds of:

-   -   Improved energy efficiency at comparable capacity    -   Improved volumetric efficiency and reduced pressure ratio    -   Reduced potential for leakage of refrigerant from the high        pressure lines of the system    -   Reduced direct GWP of the refrigerant

The currently most preferred fluids of the invention are those whosecooling capacity matches that of R-404A, whose condensing pressure islower than that of R-404A and whose energy efficiency is higher thanthat of R-407A or R-407F when compared in this manner.

It should be noted that at evaporation temperatures typical ofmedium/high supermarket temperature refrigeration systems theabove-stated performance gains are all maintained and thus the fluidsare of applicability in all commercial refrigeration applications. Infact the performance of the fluids of the invention compared to R-404Ais further improved at higher evaporation temperatures. In particularthe COP of the fluids of the invention is found to be similar or bettereven than that of R-407C.

The fluids of the invention can thus find application not only for lowstage refrigeration but also for medium high stage refrigeration and airconditioning applications.

It has also been found possible with the compositions of the inventionto exceed the performance of R-407D, a fluid which is used for certainrefrigerated transport applications as an alternative to the CFCrefrigerant R-500, for example if R-32 content in the range 16-20% isused. It is evident from the performance comparison that the capacityand COP of R-407D can be matched or bettered whilst maintainingcompressor discharge pressure at or below that of R-407D. Thus thepreviously claimed benefits of the fluids are also achieved for thisapplication.

R-32/R-161/R-134a/R-1234ze(E) Blends

Analysis of selected compositions of the invention containing 20 to 46%by weight R-32, 10 to 60% by weight R-161, 10 to 22% by weight R-134aand 8 to 60% by weight R-1234ze(E) was carried out using the samerefrigeration cycle conditions as detailed above under Example 3. Theresults are shown in Tables 35 to 105 below (see Table X above forreference).

It is found unexpectedly that the Coefficient of Performance (COP) ofthe fluids is not only higher than that of R-407A in the equivalentcycle conditions but is higher than that achievable with theR32/R125/R134a/R1234ze(E) fluids of the invention. The use of minorquantities of R-161 in place of R-125 allows further improvement of theenergy efficiency (COP), further reduction of the GWP of therefrigerant, reduction in condenser operating pressure and reduction inthe amount of R-32 required to give comparable cooling capacity. Thefluids therefore offer similar performance benefits as already stated.These fluids are especially attractive in applications and equipmentwhere mild flammability of the refrigerant can be accepted.

R-32/R-161/R-125/R-1234ze(E) Blends

Analysis of selected compositions of the invention containing 16 to 40%by weight R-32, 10 to 30% by weight R-161, 10 to 25% by weight R-125 and10 to 64% by weight R-1234ze(E) was carried out using the samerefrigeration cycle conditions as detailed above under Example 3. Theresults are shown in Tables 106 to 124 below (see Table X above forreference).

Surprisingly, the Coefficient of Performance (COP) of the fluids ishigher than that of R-407A in the equivalent cycle conditions. The useof minor quantities of R-161 allows improvement of the energy efficiency(COP) and reduction of the GWP of the refrigerant. A reduction incondenser operating pressure and pressure ratio is also observed,alongside a reduction in the amount of R-32 required to give comparablecooling capacity. The fluids therefore offer similar performancebenefits as previously stated. These fluids are especially attractive inapplications and equipment where mild flammability of the refrigerantcan be accepted.

The invention is defined by the claims.
